Kiln Drying
The process of reducing the moisture content of timber after which it is known as kiln dried. The timber is placed on stickers in a kiln which may be heated by an oil, gas or wood fired boiler. Hot water from the boiler is fed through pipes running inside the kiln. As the temerature rises the wood gives up its moisture. Excess moisture is removed by fans venting to the outside, whilst fresh air is drawn in. Care must be taken to ensure temperature and humidity are properly controlled during the drying process.
